TITLE: GCN GRB OBSERVATION REPORT NUMBER: 924 SUBJECT: GRB010126 optical observations DATE: 01/01/28 17:30:27 GMT FROM: Adalberto Piccioni at Astronomy, Bologna U. GRB010126 C. Bartolini, A. Guarnieri and A. Piccioni, Departement of Astronomy, Bologna University, and S. Bernabei, L. Fabbroni and R. Gualandi, Bologna Observatory, communicate: "We observed the error box of GRB010126 on January 27, 2001, in poor weather conditions (seeing 2".5) with the 1.5 m Loiano telescope. Two CCD frames, 13'X13', centered on the error box center reported by K. Hurley on GCN922, were obtained in R band with start times UT 01:05:00 (30 min) and UT 01:39:00 (20 min), respectively. A preliminary inspection of the two frames shows a possible variable object (r.a. 11 57 07.3, de. 49 44 26.5) not present in the DSSII-red, barely over the plate detection limit. This object, by comparison between the two frames, seems to be fading. Deeper analysis is in progress."
